SUP-2260, Forum Posts link on profile is wrong URL. Should use apps.topcoder.com/forums as the base

-- Updated link's base to app.topcoder.com/forums
-- Updated protocol from http to https to be in sync with other links across site. Further, this link requires authenticated user, hence, https makes sense.
